Put your hard effort into a 15.5 gallon Sankey
When it takes the same amount of time to do 5 gal as 10! I use a fire cutting blade on a sawzall to ripem up. Fill with allot of water to hold her steady while cutting.
You will be glad if you heed my advice, and that way you can do 5,10 and up to 12 gallon batches!
